When called upon by the party, Vix led them through the Twisted Thicket to a site of "Ancient Power" after they gifted him a statuette of a Satyr. They were hopeful he knew the location of an Element Stone but it was in fact a Feywild Portal. Here, he used the statuette to activate the portal and abandon them while they fought the Summer's Bane Beastfolk.
After the party tracked him down in the Feywild he had been petrified and lost his arm to a Petrification Spider. They saved him, healed him, then bound him for his trespasses.
Vix, under order, then led them to Exile's Henge and was invited by Reot Windwalker to join his community. The party gave him their forgiveness and saw this as a new chance for him to live a more honest life, he remains in this community to this day.
